A great way to share your most robust content, such as flash games or videos, is by using our widget sharing functionality. We highly encourage embedding sharing buttons directly into your widgets so users can share it from wherever they see it, not just when they are on your site.
A couple other features we provide for widgets is sharing them via the API and working with configurable widgets. Some of the supporting destinations to share widgets include Facebook (flash only), Windows Gadgets, iGoogle, Netvibes, Xanga, etc!
A great example of our widget sharing in action can be found on NBC.com’s video implementations:
NBC also has on page link sharing for users to share to services who don’t accept widgets:
